1. A voltage shifting data transmission system, comprising:

  • a static level-shifter having an input for a control signal within a first voltage domain and an output for a signal representing a strobe signal shifted to a second voltage domain;

    a plurality of dynamic level-shifters, each having a first input coupled to the shifted strobe signal, a second input for a respective data signal within the first voltage domain, and an output for a signal representing the respective data signal shifted to the second voltage domain; and

    an activity detector coupled to the data signals of the first voltage domain to block transition of the shifted strobe signal from the static level-shifter when the data signals are static.
